On a new Species of Laomedea; with Remarks on the Genera 
Campanularia and Laomedea. By the Rev. T. Hincxs, B.A. 
A new British species of Laomedea was described under 
the name of L. angulata, which is remarkable as being the only 
member of this genus yet discovered in which the reproduc- 
tive capsules are not axillary, but originate from the creep- 
ing fibres. Mr. Hincks also described a remarkable variety 
of Campanularia Johnstoni (Alder), which is branched, and 
bears capsules on the pedicel as well as on the fibre. In 
these two forms, the supposed distinctive characters of 
Laomedea avd Campanularia are intermingled. There was 
not, indeed, a single constant character that could be 
relied upon for the separation of the two genera, and he 
therefore proposed, with Van Beneden, to range both 
branched and simple forms under Campanularia, abandoning 
the genus Laomedea. One section, however, of Campanu- 
Jaria seemed to him entitled to distinct generic rank, that 
which includes the small and (for the most part) Sessile spe- 
cles, and for this he proposed the name Calicella. 
On some new and interesting Forms of British Zoophytes. 
By the Rev. T. Hincxs, B.A. 
A new species of Plumudaria was characterised under the 
name of P. similis, closely allied to the P. echinulata of 
Peach. Two new species of Polyzoa were also described, 
one as Avenella dilatata, the other, which exhibits a new 
generic type, as Arachnidia hippothdoides, a delicate ctenos- 
tomatous Polyzoon, curiously resembling in general appear- 
ance the well-known Hippothoa. Mr. Hincks also drew 
attention to the remarkable difference in the form of the male 
and female capsule in Halecinum Beanti and H. halecinum. 
The Rev. W. Hincxs read a paper from Mr. Alder of 
Newcastle-on-Tyne, “‘On three New Species of Sertularian 
Zoophytes.” The first, taken on the Durham coast, was 
Campanularia halecioides ; the second, taken off the North- 
umberland coast, Halecium labrosum; the third, a foreign. 
species, Halecium nanum, found amongst the Gulf weed. 
Mr. Warrneton read a paper “On the Multiplication of 
Actiniz in his Aquaria.” He described a process of repro- 
duction occurring amongst these creatures, in which a portion 
of the base becoming separated from the Actinia, split up 
into three or four portions, each giving rise to anew Actinia.
